SuSEfirewall V1 and V2 differences

Hi, Have recently changed from using SuSE V7.1 with SuSEfirewall V1 to SuSE V8.1 with SuSEfirewall V2. Now, when I check my ports at http://www.grc.com, I find my identd port 113 is marked as closed whereas before it was marked as stealth(sic) , i.e. it doesn't respond at all to probes. I'm just wondering what the thinking is behind this change. Is it simply a preferred option and easier to do with iptables than ipchains. Regards Andy
